DETAILED DESCRIPTION

A real time compounding 3D printer allows for mixing in real time liquid or powder medications and then printing the capsule. In one aspect, the ingredients may be mixed into a biopolymer that can be consumed and then allow for time release of drugs are then possible. This may be performed by inputting the drug mixture and allowing the system to precisely control all volumes and mix and dispense or print in 3D in real time.

The system may have multi-material capability. Thus, multiple materials may be used which may include any number of materials suitable for either the medication or capsules or biopolymer. Biopolymers are any polymers that are biocompatible such as polycaprolactone or materials made to be biocompatible. Suitable materials include any drug in liquid or powder form. Materials may further include flavoring agents or other ingredients. The materials themselves may have a wide range of material viscosities including viscosities in the range of 1 centipoise to more than 1 million centipoise.

A mixer as a part of the 3D printer system may provide for mixing diverse types of materials in real-time. The material may be micro-dispensed into existing capsules or micro-dispensed into 3D capsules that are printed on the 3D printer system. Additional mixing may include mixing low and high viscous materials to include mixing while heating or cool. Where drugs are mixed into the biopolymer they can then be printed in any 3D shape and size thus eliminating the need to print in capsules.

It should be understood that each 3D printed pill or custom pill may be designed and constructed according to parameters such as strengths, dosage forms, flavors, or other parameters. For particular individuals, ingredients may be excluded due to allergies or other adverse reactions. Particular ingredients may be included based on particular preferences of a user such as flavor.

It should be understood that in addition to medications the methods and systems described herein may be used for formulating nutraceuticals, nutritional supplements, or other health supplements which do not necessarily require prescriptions from a health care provider.

FIG. 1 illustrates one example of a system 10 for 3D printing. As shown in FIG. 10 a prescription 12 may be received as a set of input parameters at a control system 16. It is contemplated that the prescription 12 may be an electronic prescription from a health care provider. Either a single prescription or multiple prescriptions may be present. Prescription information may be for a particular amount of medication or active ingredient and the frequency that the medication can be taken or other instructions or directions for use. Information may include a recipe which may include a basis or chief ingredient, an adjuvant to assist its action, a corrective to prevent or lessen any undesirable effect, and a vehicle or excipient to make it suitable for administration and pleasant to the patient. Alternatively, this information may be otherwise input into the control system 16. In addition, the control system 16 may receive as input personal preferences 14 which may include preferences regarding flavoring agents or coloring agents or dosage forms. In addition, input may be received as personal preferences 14 or otherwise if the individual is allergic to certain types of potential ingredients or otherwise has adverse reactions to certain types of ingredients.

It is to be understood that because individual dosages of the medication are being created, there is a heretofore unknown level of customization that may be performed for each particular dose or across a plurality of different doses.

For example, the medication may be printed in a manner which promotes proper time release of the medication within the dose. This may be accomplished by layering the active ingredients at appropriate layers within the dosage form so that the medication is released over the time. Selection of other materials to include within the dose may be made to delay or increase the time of absorption to meet desired time release guidelines.

In another example, where a prescription (as opposed to an individual dose) is to last for a particular time period, the amount of an active ingredient may be decreased over the time period (e.g. the first dose may be significantly stronger than the last does). For example, for narcotic pain medications, the amount of active ingredient may be decreased over the length of the prescription in order to assist in avoiding dependency on the pain medications. Thus, customization may occur across a set of pills associated with a prescription.

Similarly, where an individual is taking multiple medications, multiple medications may be included in the same dose. Alternatively, where an individual must still take multiple medications, coloring agents may be added to help the individual distinguish between different doses. Alternatively, coloring agents may be used to assist an individual in determining when to take particular doses (e.g. blue bills at breakfast, yellow pills at lunch, green pills on Mondays, etc.). Thus, color coding may be used according to user preferences or across a set of medications taken by an individual to increase convenience to the user and increase compliance by the user.

In addition to color coding, it is contemplated that other forms of customization may be performed. The customization may included various types of identifying information. The identifying information may include color coding and/or may include characters or symbols or patterns including patterns encoding information such as two dimensional bar codes. In addition, different sizes or shapes may be used to identify a particular type of medication or supplement, the volumetric concentration of a particular ingredient, the schedule for taking the dose, or other information. The identifying information may also include information identifying the patient, or other information from a prescription, information identifying the 3D printer, or other information.

Once properly parameterized based on various inputs including from one or more prescriptions 12, personal preferences 14, additional parameters set by pharmacists or system parameters. For example, the system may provide for accessing databases of drug interactions and not allow certain drugs to be combined which would have the potential for adverse reactions.

A mixer 18 is shown. One or more mixers may be present as the system 10 may support multiple types of materials. The mixer 18 may receive liquid 20 and/or powder 22. The mixer 18 may be used for mixing diverse types of materials in real-time. Materials from the mixer 18 may be conveyed through the 3D printer 20 to one or more micro-dispensers 24. It is to be understood that the mixer 18 may be integrated into the 3D printer 20 in various ways and at various locations as may be appropriate for a particular embodiment. For example, in one embodiment, each micro-dispenser 24 may have its own mixer associated with it. A heating unit 28 or cooling unit 30 may be associated with the mixer 18 in order to alter temperature of the mixture so as to control viscosity of the mixture in a manner that will support printing. Any number of different types of heating and/or cooling may be used.

The micro-dispensers 24 may 3D print or dispense the materials in various dosage forms 26. The 3D printer may print or dispense the materials in multiple layers under computerized control to build-up the materials into dosage form. For example, the personalized medications may be dispensed into pre-existing capsules. Thus, for example, liquids or powders may be dispensed into the pre-existing capsules and then the capsules may be assembled or sealed. It is contemplated that a seal may be printed on the capsule to seal the capsule. The capsules may be placed in trays or on reels to assist in this process. Alternatively, the capsules themselves may be printed. Of course, capsules are not necessary as biopolymers may be printed in any number of different forms, including those which may be set by user preferences or according to prescription. For example, medication may be presented as strips, in sub-lingual form, or other types of oral dosages.

It is also to be understood that the personalized medicine described herein is not to be restricted to oral doses as other types of delivery systems are contemplated. For example, where medication is to be delivered as a patch, the patch or portions of the patch may be printed with the system in order to include a proper dose of the medication(s). Identifying information 32 may be included on the personalized medicine in the form of characters, symbols, patterns, or otherwise. Identifying information may also be conveyed based on size, shape, and coloring.

FIG. 2 provides an overview of one methodology. In step 40, parameters for personalized medication or supplements are received at a 3D printer. The parameters may vary to include personal preferences, details of a prescription, or other parameters. The parameters define at least one ingredient. In step 42, one or more ingredients are mixed at a 3D printer. During mixing or in preparation for mixing the ingredients may be heated or cooled in order to obtain a desired viscosity. In step 44, the ingredients are micro-dispensed or 3D printed into dose form at the 3D printer.

The invention is not to be limited to the particular embodiments described herein. In particular, the invention contemplates numerous variations in the form of dose, the types of materials used, the specific type of micro-dispensing performed, the manner in which the process is controlled, the inputs to the system, and other variations. The foregoing description has been presented for purposes of illustration and description. It is not intended to be an exhaustive list or limit any of the invention to the precise forms disclosed. It is contemplated that other alternatives or exemplary aspects are considered included in the invention. The description is merely examples of embodiments, processes or methods of the invention. It is understood that any other modifications, substitutions, and/or additions can be made, which are within the intended spirit and scope of the invention.
